It's almost Christmas and I won't have much time for a couple of weeks but I thought I'd have a look inside the engine.
First the heads and cylinders removed. You can see in the photo below that the pistons are in good condition and have been purposely scuffed with emery to hold oil.
Looking at the photo of the top of the piston it's obvious that this piston has never been run. There is no colour on it at all.
The bores are in excellent condition.
I removed the other cylinder and it was in the same condition as this one. I'll split the crankcases after Christmas. I've never worked on an engine with vertically split cases before (excepting lawnmowers) but I guess it can't be too difficult. Gotta work out what's wrong with the gearbox.
